Performance analysis of solar still using sensible heat materials for saline water

Natural water resources are polluted in large extent that affects human and other living organisms. Therefore, water purification has gained an important attention in recent years. Among the various methods adopted for water purification, solar still is a device used to purify the saline and polluted water. Various sensible heat materials such as charcoal, pebbles and gravels are used in the solar still. These materials are used to increase the rate of evaporation and to enhance the performance of solar still. The experimental results proved that the sensible materials that were using the combination of charcoal with gravels resulted in high yield. From this experiment, the rate of discharge for combination of pebbles with gravels, pebbles with charcoal and gravels with charcoal are 200%, 240% and 290%, respectively.
